The Coachella Music Festival kicked off in California April 13 headlined by Beyonce, Cardi B and Post Malone. But the surprise of the show was when internet sensation Mason Ramsey aka the Walmart Yodeling Kid took the stage.

Ramsey, 11, became famous after a video of him yodeling a Hank Williams song went viral. That audio was then remixed and has become so popular that even Boston Red Sox pitcher Joe Kelly uses it, as his walk-in song.

On Saturday April 14, Ramsey took the Coachella stage, surprising fans. He was invited by Post Malone to come to California and even got to meet Justin Bieber.

And to top it all off, Ramsey was lucky enough to be on Ellen earlier in the week, admitting this was his first flight ever and first time drinking sparkling water.
